Is there a way to check if @Environmentobject exists swiftui

Question

I have a view hierarchy where sometimes there is a chance that an @EnvironmentObject is not resolved. Is there a way to check if such @EnvironmentObject exists before accessing its value?

Something like below:

struct SampleView: View {
    @EnvironmentObject var someStateObj: SomeStateObjectType
    var body: some View {
        Button("Test") {
            // Line below will not work...
            if someStateObject != nil { /* Do Something */ }
        }
    }
}
